Poly Locks
The PRW 1200123 12-Point Poly Lock Set are a set of 12-point rocker arm lock nuts designed to secure rocker arms on engines with 3/8 in. stud diameters. These polylock-style nuts provide reliable clamping force that helps maintain proper valvetrain geometry and resist loosening under high RPM or vibration, ideal for performance, racing or rebuilt engines where durable rocker arm retention is critical.
PRW 1200123 12-Point Poly Lock Set Features:
- 12-point polylock rocker arm nuts for positive grip on rocker studs and reduced chance of loosening under load
- Designed for 3/8 in. stud diameter applications commonly found in many performance engines
- 0.550 in. outside-diameter shank for compatibility with many aluminum and steel rocker arms without interference
- Ideal for use with rocker stud girdles or traditional stud/rocker systems where secure lock-down is required
PRW 1200123 12-Point Poly Lock Set Notes:
- Not all polylock types fit every rocker arm style, check outside diameter and head clearance with your specific rocker arms
- These nuts are for high-performance valvetrain applications where vibration and RPM can cause conventional nuts to back off
